Plumes d'azur by Roland Libois, 2018

Histoire naturelle du martin-pêcheur d'Europe

The kingfisher, one of the most "exotic" European birds by its colors, has always aroused the wonder of those who manage to observe it. A predator of small fry, it needs, to complete its life cycle, aquatic environments rich in fish and especially soft banks with a vertical or slightly concave profile...

where it can dig the burrow in which the eggs are laid. Formerly destroyed by man because of the damage to fish farms of which it was accused, it is now protected by law, but its nesting sites are not sufficiently respected. Many rivers are seriously polluted, their banks reprofiled, rectified, coated, even concreted: so many attacks on the capacity of the environment for the kingfisher. The book tells, in a few chapters, the scientific elements to understand the life of the kingfisher. After the rigorous presentations (etymology, ancient history, zoological classification, morphology), we dive into the intimate life of the bird: reproduction cycle, ecological perspective, but also ethology. Demography (births and deaths) plays a crucial role in understanding fluctuations in numbers, which are closely linked to winter mortality and the production of young. Behavioral plasticity is revealed by particular cases, notably by means of molecular genetics. Finally, movement and migration, diet, social systems and predators are discussed in this book.
